! WARNING
! WARNING
Hydraulic hoses and tubing must be
inspected on a daily basis for leaks, cuts,
abrasions,
damage
and
improper
clearance along any mounting frame for
hidden damage before the unit is put into
service. Replace damaged hoses or hoses
you suspect are damaged before the
system is returned to service! Hoses must
be replaced every two years. Failure to
properly inspect and maintain the system
may result in serious injury.
Hydraulic cylinders can be holding a
function in a certain position when
thepump is OFF. An example of this is a
function being held in the lift or partial lift
position by the cylinders. If a hydraulic
line is removed or the hydraulic circuits or
controls are being worked on, gravity may
allow the function being held in position to
drop. All workers and personnel must
remain clear of these areas when working
on or operating the hydraulic system.
Block and secure all devices and
functions which apply before beginning
work or operation. Failure to comply with
this can result in serious injury or death.
! WARNING
Hydraulic systems are hot. DO NOT
TOUCH! Serious personal injury may
result from hot oil. When you have
completed working on the hydraulic
system, thoroughly clean any spilled oil
from the equipment. Do not spill any
hydraulic fluids on the ground. Clean any
hydraulic fluids from your skin as soon as
you have completed maintenance and
repairs. Dispose of used oil and system
filters as required by law.
! WARNING
Any hydraulic pipe which is replaced must
conform to SAE J1065 specifications. If
incorrect hydraulic pipe is installed, the
hydraulic system may fail, causing
serious injury. Damaged or leaking
fittings, pipes or hoses must be replaced
before the system is returned to service.
! WARNING
! WARNING
Use correct hoses, fittings, and adapters
with the correct SAE rating when
replacing hoses to prevent possible
serious injury. Always replace hoses,
fittings, and adapters with replacements
that have a proper, suitable, working
pressure rating. Replacement hoses must
be of the correct length and must comply
with the hose manufacturer’s and
Oilgear’s installation guidelines and
recommendations.
DO NOT heat hydraulic pipe. The carbon
content of this steel tube is such that if
heated for bending, and either water or air
quenched, the pipe may lose its ductility
and thereby be subject to failure under
high pressure or hydraulic chock
conditions. Serious injury can result.
Damaged or leaking pipes must be
replaced before the system is returned to
service. Please contact Oilgear if you
require assistance or have questions.
! WARNING
! WARNING
Hydraulic hoses have the SAE ratings
marked on the hose to assist you in
selecting the correct hose. The same manufacturer must supply any replacement
hydraulic hoses and fitting assemblies. As
an example: Brand “X” hose and brand “Y”
fitting will not normally be compatible. No
“Twist” is allowed in the hydraulic hoses.
“Twist” may result in premature hose
failure. This can cause serious injury.
Please contact Oilgear for assistance when
required.
All hydraulic pressure must be relieved
from the hydraulic system prior to removing
any components from the system. To
relieve the hydraulic pressure from the
hydraulic system, turn off the motor and
operate the control panel with the key in the
ON position. Failure to comply can result in
serious injury. If you have any questions
concerning relieving the hydraulic pressure
from the system, please contact Oilgear.

Service Instructions
PREPARATION AND
INSTALLATION
! WARNING
MOUNTING
Pump Without Reservoir - The pump can be
mounted in any position. But, the recommended
mounting position is with the driveshaft on a
horizontal plane. Secure the pump to a rigid
mounting surface.
Pump With Reservoir - These pumps are usually
fully piped and equipped. It may be necessary to
connect to a super-charge circuit when used.
Mount reservoir on level foundation with the
reservoir bottom at least six inches above floor
level to facilitate fluid changes.
Running the pump in NEUTRAL position
(zero delivery) for extended periods
without a supercharge circuit can damage
the pump. The system and pump must be
protected against overloads by separate
high pressure relief valves. Install bleed
valve(s) at the highest point(s) in system.
POWER
Power is required in proportion to volume and
pressure used. Motor size recommendations for
specific applications can be obtained from The
Oilgear Company. Standard low starting torque
motors are suitable for most applications.
CAUTION
PIPING AND FITTINGS
Refer to the referenced Oilgear Piping Information
Bulletin 90011 and individual circuit diagram before
connecting the pump to the system. Inlet velocity
must not exceed 5 fps (1,5 mps). Inlet should be
unrestricted and have a minimum of fittings.
NOTE
DO NOT use an inlet strainer.
Horizontal Mounting - Arrange line from the highest
“case drain” or “alternate case drain” so the case
remains full of fluid (non-siphoning). Case pressure
must be less than 25 psi (1,7 bar). For higher case
pressures and the special shaft seals required,
contact our Customer Service. Each drain line
must be a separate line, unrestricted, full sized and
connected directly to the reservoir below the lowest
fluid level. Make provisions for opening this line
without draining (siphoning) reservoir.
Vertical Mounting - Refer to referenced Oilgear
“Installation of Vertically Mounted Axial Piston
Units,” Bulletin 90014.
Bulletin 947070-B
DO NOT start or stop unit under load
unless system is approved by Oilgear. It
may be necessary to provide delivery
bypass in some circuits.
DRIVE
Verify rotation direction plate on the pump's housing.
Clockwise pumps must be driven clockwise and
counterclockwise
pumps
must
be
driven
counterclockwise. Use direct drive coupling. Size
and install coupling per manufacturer's instructions.
CAUTION
DO NOT drive the coupling onto the pump
driveshaft. If it is too tight, it may be
necessary to heat coupling for installation.
Refer to manufacturer's instructions.
Misalignment of pump shaft to driver's shaft should
not exceed 0.005 inches (0,13 mm) Total Indicator
Readout (TIR) in any plane.

FILTRATION
Keep the fluid clean at all times to ensure long life
from your hydraulic system. Refer to the referenced
Oilgear Filtration Recommendations bulletin 90007
and Oilgear Contamination Evaluation Guide
Bulletin 90004. Oilgear recommends use of a filter
in the pressure or return line. Replace filter
element(s) when the filter condition indicator
reaches change area at normal fluid temperature.
Drain and thoroughly clean filter case. Use
replacement element(s) of same beta 10 ratio
(normally a ratio of 4 with hydraulic oils).
FLUID COOLING
When the pump is operated continuously at the
rated pressure or frequently at peak load, auxiliary
cooling of the fluid may be necessary. Fluid
temperature should not exceed limits specified in
the referenced Oilgear Fluid Recommendations
Bulletin 90000.
AIR BREATHER
On most installations, an air breather is mounted
on top of fluid reservoir. It is important for the
breather to be the adequate size to allow air flow in
and out of reservoir as fluid level changes. Keep
the breather case filled to the “fluid level” mark.
About once every six months, remove cover, wash
screen in solvent and allow screen to dry, clean
and refill case to level mark and install screen.
Refer to the manufacturer's recommendations.

FLUID, FILLING AND STARTING
RECOMMENDATIONS
Refer to instruction plate on the unit, reservoir,
machine and/or reference, Fluid Recommendations
bulletin. Fire resistant fluids and phosphate ester
fluids can be used in accordance with fluid
manufacturer's recommendations.
1. Pump all fluid into reservoir through a clean
(beta 10 ratio of 4 or more) filter. Fill reservoir
to, but not above, “high level” mark on the sight
gauge.
2. Remove case drain line and fill pump case
with hydraulic fluid.
3. Turn driveshaft a few times by hand with a
spanner wrench to make sure parts rotate.
With pump under “no load” or with pump control at
NEUTRAL:
4. Turn drive unit ON and OFF several times
before allowing pump to reach full speed. The
system can usually be filled by running the
pump and operating the control.
5. The fluid level in the reservoir should decrease.
Stop the pump. DO NOT allow the fluid level to
go beyond the “low level.” If the level reaches
“low level” mark, add fluid and repeat step.
NOTE
With differential (cylinder) systems, the fluid
must not be above “high level” when the
ram is retracted or below “low level” when
extended. Bleed air from the system by
loosening connections or opening petcocks
at the highest point in the system. Close
connections or petcocks tightly when solid
stream of fluid appears.

PRINCIPLE OF OPERATION
The areas on either end of the control piston are
the same and the pressure acting on either end is
the same. The resultant hydraulic forces on the
ends of the control piston cancel each other out
(the control piston is balanced), and the force of the
control piston spring (20) controls the control piston
position (19).
Rotating the driveshaft turns the splined cylinder
(38), which contains the pumping pistons (39).
When the cylinder rotates, the pistons move in and
out within their bores as the shoes ride against the
angled swashblock (29).
OILG0020
Figure 2. Cut-a-way of a Typical “PVM”
Pump (01010)
Full Stroke Operation - Figure 3
NOTE
Numbers in parentheses represent item
number in parts list and drawings.
The control piston (19) positions the control pin
(31) and pump swashblock (29) so the pump will
deliver maximum volume to raise pressure in the
system.
Raising Pressure
Pump delivery (and resultant pressure) is fed to
both sides of the control piston (19). Pressure to
the unloading side (C) of the control piston is
direct. Pressure to the bias side (D) of the control
piston is maintained by the respective control.
As the cylinder rotates, the individual piston bores
are connected, alternately, to the crescent shaped
upper (P) and lower (S) in the valve plate. While
connected to the lower side (suction) S, each
piston moves outward OUT, drawing fluid from S
into the piston bore until its outermost stroke is
reached. At this point, the piston bore passes from
the lower crescent S to the upper crescent P.
While rotating across the upper crescent port, each
piston moves across the angled swashblock face
and then each piston is forced inward IN. Each
piston then displaces fluid through the upper
crescent to P until its innermost stroke is reached.
At this point, the piston bore passes from the upper
to the lower crescent again and the cycle is
repeated.
The angle of the swashblock determines the length
of the piston stroke, (the difference between
outermost and innermost position) which
determines the amount of delivery from the pump.
If the stroke angle is one-half of the stroke, the
piston stroke is one-half and the pump delivery is
one-half.
Note that the flow through the PC control cartridge
(3-1) is blocked.

Relatively small variations in system flow
requirements can be accommodated for in the
mentioned operational mode. When pump outlet
pressure decreases below the preset pressure
setting of the PC Control Cartridge, the PC Control
Cartridge closes. The sequence spool spring (53)
repositions the sequence spool to open the flow
path. This provides for an unobstructed flow path to
the bias side of the control piston so the pump will
be responsive to increased system flow demand.

Pressure Compensating - Figure 4
When pump outlet pressure reaches the preset
pressure setting of the PC Control Cartridge, bias
pressure D (pressure on the spring side of the
control piston) is relieved by the PC Control
Cartridge. Exhaust flow from the PC Control
Cartridge is ported to the pump case via the
sequence spool (54). The resulting pressure drop
across the sequence spool due to the exhaust flow
moves the spool to block the flow path. All flow to
the PC Control Cartridge is now provided via the
stability orifice OP2 (68).
Blocking the flow path and requiring all control flow
to pass through OP2 minimizes case drain leakage
and provides a means of stability adjustment for a
wide range of system requirements. The decrease
in bias pressure results in a pressure differential
across the control piston (19). The control piston is
no longer balanced and the pressure on the
unloading side of the control piston forces the
control piston to compress the control piston spring
(20). The control piston moves the control pin and
shifts the swashblock to a position that provides
less flow output from the pump. Flow output from
the pump is then controlled to maintain the preset
pressure setting of the PC Control Cartridge. When
the outlet port of the pump is blocked, the
swashblock is positioned so the pump delivers just
enough volume to provide for internal losses and
required control flow.

Principal of operation for remote pressure

The supply port of the remote pressure control
valve needs to be ported to the RP port on the
valve plate (43). The exhaust from the remote
pressure control valve needs to be ported to the
HP port on the valve plate. When pump outlet
pressure reaches the preset pressure setting of the

minimizes case drain leakage and provides a

NOTE
NOTE
Failure to port the exhaust of the remote
pressure control valve to the HP port will
result in significantly higher case drain
leakage.
The RP lines of multiple pumps cannot be
tied together for unloading or controlling
with a common remote pressure control
valve. Each pump requires a dedicated
valve.

The decrease in bias pressure results in a pressure

Load Sense Port
OILG0118
Figure 6. Standard Load Sensing with Pressure
Compensating Override
Standard Load Sensing with Pressure
Compensator Override - Figure 6
The parts configuration for the Standard Load
Sense control is similar to the Pressure
Compensator control except for the installation of a
plug. All other components are unchanged. A 1/16
inch pipe plug is supplied with all new pumps. The
plug is installed in a blind hole next to the LS port
for all pumps originally shipped as a Pressure
Compensator control or Adjustable Load Sense
control. The plug (69) is already installed in the
correct location (and the blind hole is empty), if the
pump was originally shipped as a Standard Load
Sense.
To convert to a Standard Load Sense from a
Pressure Compensator control, install the pipe plug
(69) deep into the LS port of the valve plate as
shown in Figure 6.
NOTE
The pipe plug threads start approximately
1.7 inch (0.043 mm) from the port spotface.
Standard Load Sense control requires the load
sense line (pressure signal from downstream of an
orifice or flow control valve) be attached at the LS
port on the valve plate assembly. Load sense
pressure is ported via the sequence spool and
stability orifice to the bias side of the control piston
(19). The pressure differential across the system
14
THE OILGEAR COMPANY
Bulletin 947070-B
flow control is therefore equal to the pressure
differential across the control piston; when the
pressure differential reaches the non-adjustable
preload force of the control spring, the control
piston moves toward the neutral position. The
control piston moves the control pin and shifts the
swashblock to a position that reduces pump
delivery to maintain a constant, preset pressure
differential across the flow control valve. The preset
pressure differential is 150 to 210 psi (10,3 to 14,5
bar). If the pressure differential across the flow
control valve is decreased, the control piston spring
(20) moves the control piston in the full stroke
direction until pump delivery is increased
sufficiently to reach the preset load sense
differential pressure. When the pump outlet is
blocked and the load sense pressure is allowed to
go to drain pressure, the swash is positioned so
that the pump delivers just enough volume to
provide for internal losses and required control flow
at a standby pressure equal to the preset pressure
differential of 150 to 210 psi (10,3 to 14,5 bar).
The pressure compensating function will override
the load sense control and, if necessary, further
reduce pump delivery when the load sense
pressure reaches the preset pressure of the PC
Control Cartridge.

Adjustable Load Sensing w/ Pressure
Compensator Override - Figure 7
The Adjustable Load Sense control functions
similar to the Standard Load Sense control except it
is adjustable from 150 to 600 psi (10,3 to 41,4 bar).
The Adjustable Load Sense Cartridge is located
adjacent to the PC Control Cartridge on the valve
plate. The Adjustable Load Sense does not require
the installation of the 1/16 inch pipe plug in the
standard load sense port as previously described.
The standard load sense port should be plugged
with an SAE #4 plug. Adjustable Load Sense
control requires the load sense line [pressure
signal from downstream of an orifice or flow control
valve] be attached to the end of the Adjustable
Load Sense Cartridge.
When load sense pressure differential reaches the
preset pressure setting of the Adjustable Load
Sense Cartridge, bias pressure D [pressure on the
spring side of the control piston (19)] is relieved by
the Adjustable Load Sense Cartridge. Exhaust flow
from the Adjustable Load Sense Cartridge is
ported to the pump case via the sequence spool.
The resulting pressure drop across the sequence
spool (54) due to the exhaust flow moves the spool
to block the flow path. All flow to the Adjustable
Load Sense Cartridge is now provided via the
stability orifice OP2 (68). Blocking the flow path
and requiring all control flow to pass through OP2
minimizes case drain leakage and provides a
means of stability adjustment for a wide range of
system requirements.
The decrease in bias pressure results in a pressure
differential across the control piston (19). The
control piston is no longer balanced and the
pressure on the unloading side of the control piston
forces the control piston to compress the control
piston spring (20). The control piston moves the
control pin and shifts the swashblock to a position
that provides less flow output from the pump. Flow
output from the pump is then controlled to maintain
the preset pressure differential setting of the
Adjustable Load Sense Cartridge. When the outlet
port of the pump is blocked, the swashblock is
positioned so the pump delivers just enough
volume to provide for internal losses and required
control flow at a standby pressure equal to the
differential pressure setting of the Adjustable Load
Sense Cartridge.

Relatively small variations in system flow
requirements can be accommodated for in the
mentioned operational mode, but, when pump
outlet pressure decreases below the preset
differential pressure setting of the Adjustable Load
Sensing Cartridge, the Adjustable Load Sensing
Cartridge closes. The sequence spool spring (53)
repositions the sequence spool to open up the flow
path. This provides for an unobstructed flow path to
the bias side of the control piston so the pump will
be responsive to increased system flow demand.
The pressure compensating function will override
the load sense control and, if necessary, further
reduce pump delivery when the load sense
pressure reaches the preset pressure of the PC
Control Cartridge.
NOTE
Electronic Proportional Pressure Compensator
with Override - Figure 8
The Electronic Proportional Pressure Compensator
functions the same as the Pressure Compensating
Control (refer to Figure 4) except the PC Control
Cartridge is electrically controlled. An electrical
signal is used to proportionally increase or
decrease the pressure compensator setting with
increasing current. A manually adjustable PC
Override Valve enables the user to set the
maximum desired pressure compensator setting.
An Adjustable Load Sense control is also
available with a bleed-off feature. This
cartridge internally vents load sensing
pressure to case via an orifice in the
cartridge and the sequence spool when the
control is not active or the system is
shutdown.

TESTING AND ADJUSTING
DISASSEMBLY
Refer to Figures 9 through 15 for your series of
pump.
! WARNING
Shut the pump OFF and release pressure
from the system before disassembling
components. Failure to comply with these
instructions could result in personal injury
or death. Blocking the pressure line
between the pump and the system (or
pump) high pressure relief valve will result
in damage and could result in serious
personal injury.
NOTE
When disassembling or assembling the
pump, choose a clean, dry, dust and sand
free area where no traces of abrasive
particles are in the air which can damage
the pump and system. DO NOT work near
welding, sandblasting, grinding benches or
similar conditions.
PISTON PUMP
To check for a worn piston pump, make a leak
measurement test from the case drain while the
pump is under pressure. After the unit is warm,
either install a flow meter in the drain line or have
the flow from the drain line directed into a large
container or reservoir. The pump case must remain
full of fluid during this test.
Always make sure the fittings are clean on
the outside before removing them from
their connections. Make sure they are
capped and plugged when removed. Place
them on a clean surface and in a clean rag
or container until they are reinstalled.
When cleaning parts which have been
disassembled, it is important to use
CLEAN cleaning solvents and parts are
allowed to dry. All tools and gauges should
be clean prior to working with the system
and use new, CLEAN lint free rags to
handle and dry parts.
CAUTION
DO NOT run a pump on stroke against a
blocked output unless it is protected by a
high pressure relief valve and then run no
longer than necessary to check slip. Limit
discharge to prevent dropping reservoir
fluid below low level.
With an accurate high pressure gauge in the
pressure line, start the pump and stall (or block)
output device to raise system pressure to
maximum (as set by system relief valve). Read the
measurement on the flow meter or time and
measure the case drain flow used to fill a known
size container and calculate the flow rate in terms
of cubic inches per minute (cipm). The leakage
should conform to Table 5.
NOTE
Additional leakage indicates wear, but
does not become critical until it impairs
performance.
The cleanliness of working on this pump or
the hydraulic system is extremely important
to the safety and reliability of the pump and
the system.
! WARNING
DO NOT attempt to remove or install any
components or assembly while the pump
and system is running. Always stop the
pump, shut OFF the power and release
pressure from the system before servicing
or testing. Be sure provisions have been
made so the case drain line can be
disconnected from the unit without
causing the line to drain (siphon) the
reservoir.
1. Disconnect case drain line(s).
2. Drain pump case. If drain pump case plugs are
inaccessible, it may be necessary to remove
the pump from the mounting and drive motor
before draining it.

DISASSEMBLY (Continued)
CAUTION
! WARNING
Seek assistance from others and use of a
hoist and/or proper lifting techniques to
prevent personal injury.
NOTE
Tag similar parts (particularly screws, plugs
and O-rings) during disassembly to make
sure they don't become confused with
similar parts and to ensure they will be
returned to their original location. Do not
remove (locator) roll pins unless they are
deformed or need to be replaced.
3. After removing the pump from the mounting
and before disassembly, cap or plug all ports
and clean the outside of unit thoroughly to
prevent dust from entering the system.
NOTE
Depending on what part or parts are to be
inspected, it may not be necessary to
completely take apart all assemblies.
Do not damage the faces of the port plate
and the matching faces of both the valve
plate and cylinder barrel.
1. Block the unit on bench with driveshaft
horizontal.
2. Remove valve plate assembly (45) by removing
four socket head cap screws (50 and 56) and
the valve plate assembly. When used, shaft
coupling (57) with retaining rings (58), if used,
will come with valve plate assembly. The port
plate (43) is located on the valve plate
assembly by a dowel pin. Remove the port
plate from the valve plate assembly.
The control sequence valve can be removed, if
necessary by:
(A) Removing the sequence valve spool plug
(51) with the O-ring (52).
(B) Withdrawing sequence valve spool spring
(53) and sequence valve spool (54).
VALVE PLATE GROUP
If another pump is coupled with a thru-shaft pump
or other device coupled to the rear of the pump, it
will be necessary to remove that unit and O-ring
(59). If thru-shaft convertible cover (63) is used,
remove the socket head cap screws (64) and
O-ring (62). Also remove screw (61) and thru-shaft
coupling spacer (60).

for cracks and/or signs of excessive wear, make
sure it does not bind in the control piston (19).
Make sure the control piston does not show signs
of excessive wear and it slides smoothly in the
control cylinder bore. Check OP2 (68) to make sure
the orifice is not blocked. Replace if necessary or if
you suspect damage.
VALVE PLATE GROUP
Inspect the valve plate (45) and port plate (43)
surfaces which mate with each other, and the rear
of the cylinder barrel (38) for excessive wear
(scuffing and polishing are normal). Remove minor
defects by lightly stoning the surface with a hard
stone which is flat to within 0.001. (0,03 mm).
NOTE
Be sure to stone lightly. Any excessive
stoning will remove the hardened surface.
If wear or damage is extensive, replace the
component(s).
Check:

•
the fit of the control sequence valve spool
(51) in the port plate. It should move
smoothly and freely in the bore.
•
the sequence valve spool spring (53) for
cracks or signs of fatigue. It should also be
able to move (compress and decompress)
smoothly and freely in the bore.
•

SWASHBLOCK GROUP
Inspect the swashblock (29) for wear and scoring. If
defects are minor, stone the swashblock lightly. If
damage is extensive, replace the swashblock.
NOTE
ROTATING GROUP
Inspect cylinder barrel (38) piston bores and the
face which mate with the port plate (43) for wear
and scoring. Remove minor defects on the face by
lightly stoning or lapping the surface.
Inspect the hydrodynamic cylinder bearing (35) for
damage and replace if necessary. Check all piston
and shoe assemblies (38) to be sure they ride
properly on the swashblock (29).
NOTE
Be sure to stone lightly. Any excessive
stoning will remove the hardened surface.
If wear or damage is extensive and defects
cannot be removed, replace the cylinder
barrel.
See Figure 10. Check each shoe face for nicks
and scratches, and the shoe for smooth pivot
action on the piston.
NOTE
If one or more piston/shoe assembly needs
to be replaced, replace all the piston/shoe
assemblies. When installing new piston/
shoe assemblies or the rotating group,
make sure the pistons move freely in their
respective bores.
Be sure to stone lightly. Any excessive
stoning will remove the hardened surface.
If wear or damage is extensive and defects

the
swashblock.
Compare the saddle bearing (30) thickness in a
worn area to thickness in an unworn area. Replace
saddle bearings if the difference is greater than
0.015 inches (0,4 mm).
Check the mating surface of swashblock for cracks
or excessive wear. The swashblock movement in
the saddle bearings must be smooth. Replace if
necessary.
There is a small hole in the swashblock of the
saddle bearing (where saddle bearing plugs into
pump housing). This hole “ports” fluid through the
swashblock to the face of the saddle bearing
(providing lubrication). Check this hole to make
sure it is open.
NOTE
Be sure to stone lightly. Any excessive
stoning will remove the hardened surface.
If wear or damage is extensive and defects
cannot be removed, replace if necessary
or if you suspect them of being bad.
DRIVESHAFT GROUP
Check:
•
the shaft seal (24) for deterioration, cracks
or its ability to seal. (It should hold its shape
when it is pressed.) Replace if necessary
(press-out).
•
the shaft bearing (26) for galling, pitting,
binding or roughness.
•
the rear shaft bearing (67 or 77).
•
the shaft and its splines for wear. Replace
any parts necessary.

1. Place seal retainer (25) in its bore.
See Figures 11, 12 and 13. Follow the disassembly
procedures in reverse for re-assembling the pump.
During assembly, install new gaskets, seals and
O-rings. Apply a thin film of CLEAN grease or
hydraulic fluid to sealing components to ease
assembly. If a new rotating group is used, lubricate
thoroughly with CLEAN hydraulic fluid. Apply fluid
generously to all wear surfaces.
3. Insert the driveshaft assembly (21) through the
shaft seal (24), into the case, through the hole
in the saddle bearing and swashblock until the
front driveshaft bearing bottoms in its bore.
Lock in place with bearing retainer ring (28).

AFTER SALES SERVICES
SERVICE SCHOOLS
At Oilgear we build products to last. It is the nature
of this type of machinery to require proper
maintenance regardless of the care we put into
manufacturing. Oilgear has several service
programs in place to help you.
Oilgear conducts training to train your maintenance
personnel. “General” hydraulic or electronic
training is conducted at our Milwaukee, Wisconsin
plant on a regular basis. “Custom” training,
specifically addressing your particular hydraulic
and electro-hydraulic equipment can be conducted
at your facilities.
STAY-ON-STREAM SERVICE
By signing up for Oilgear's Stay-On-Steam
program, you can prepare for problems before they
happen. Certain field tests such as fluid testing,
slip testing and electronic profile recording
comparisons can be performed by our field service
people or your own factory trained personnel.
These tests can indicate problems before they
become “down-time” difficulties.

SPARE PARTS AVAILABILITY
Prepare for your future needs by stocking Oilgear
original factory parts. Having the correct parts and
necessary skills “in-plant” enables you to minimize
“down-time.” Oilgear has developed parts kits to
cover likely future needs. Oilgear Field Service
Technicians are also ready to assist you and your
maintenance people in troubleshooting and
repairing equipment.
